Applying this passage to the general thinking used when planning e.g. a project makes sence: First you survey and measure "the ground" i.e the context of the project. Then you estimate, that is take educated guesses based on your surveys, to find out the numbers needed to do actual calculations. Then you calculate, based on your guesses. So, the first two terms would relate to evaluating the enemy, solely, while the third one deal with assessing what you've found in relation to your own army (or in the case of project management, your own assignment). #
